Use your computer or smartphone to easily find a Quest Diagnostics location and make an appointment if you wish.

Some healthcare providers collect samples for laboratory tests in their offices, but others do not. If your practitioner provided you with an order (a prescription or test requisition form) for a test, you will need to visit one of our Patient Locations to have your sample collected. Learn how to find the Quest Diagnostics location that is the most convenient for you and the other steps necessary to prepare for a test and make your visit as short as possible.

Finding a Patient Location Is Easy

Simply use our online tool or mobile app to find a location convenient for you. With approximately 2,000 patient locations nationwide, it will be easy to find one that is convenient for you—whether it is close to home, work or your doctor’s office. You will see multiple locations, along with their hours, contact information and maps. Enter your starting address and you will get printable directions.

Make an Appointment—or Not

Appointments are encouraged, but are not mandatory. Use our online tool or mobile app to make an appointment. You will be able to see available appointments across multiple locations. If you prefer not to make an appointment, please be aware that our locations are usually busiest in the early morning when patients who have to fast before testing often choose to arrive. You may prefer to come later in the day, when your wait is likely to be shorter.

Put Your Smartphone to Good Use

You can also use your smartphone to find the most convenient location and make an appointment. Go to QuestDiagnostics.com from your mobile phone or download a free mobile app, which can automatically detect your location and suggest the patient locations closest to you.
